[PATCH] arm: dts: sc594: Update sc594 EZKIT GPIO polarities

[Caleb Ethridge]

Hi Greg,

Thanks for the feedback. I will send a v2 of the patch with some more information in the commit message.

Thanks,
Caleb

Hi Caleb,

+CC: Philip and Utsav, it looks like git-email did not pick up the cc
output from get_maintainer.pl.

Can we add a bit more detail to the commit message? Were the GPIO
polarities incorrect before, or are the polarities different between
two revisions of the SOM? We want to make sure that if a customer with
an older SOM uses mainline and finds that they cannot access octal spi
flash, that they can find information saying specifically that their
version is not supported by default.

I assume this will be similar to the corresponding change for the
SC598 that I mentioned caused all SPI flash to stop working for me on
Rev C/D. Luckily on the SC594 SOM the flash conflict is different, so
I don't anticipate it to prevent it from running entirely, but I do
want people to know why if they see strange behavior.

Thanks,
Greg
